Parameter is disabled if active mode is not Spectrum Analyzer
or a connection has not been established at your specified IP
address.
The external source start and stop frequencies are offset from
the analyzer start and stop frequencies by the specified amount
when the state is set to ON.
If the calculated external source start or stop frequency exceeds
the frequency range of the external source, the sweep is stopped
until you adjust the analyzer Start Frequency, Stop Frequency,
Frequency Offset (if ON) or the harmonic (if ON) such that the
frequency range can be swept by the signal source and analyzer
simultaneously. Once the frequency range of the external source
is valid, the sweep will resume.
The analyzer Start Frequency + Frequency Offset must be
greater than the external source Minimum Frequency + 1
Bucket Width.
The analyzer Stop Frequency + Frequency Offset must be less
than the external source Maximum Frequency – 1 Bucket
Width.
